Finally, RNA profiling of lung epithelial cells (BEAS-2B) expressing a mutant allele of PIK3 (E545K) identified a network of transcription factors such as MYC, FOS and HMGA1, not previously recognised to be associated with aberrant PI3K signalling in lung cancer.
Activation to a large extent of the phosphatidylinositol 3-kinase (PI3K)/Akt pathway and mutations in the p53 gene are involved in lung cancer therapeutic resistance.
Common molecular drivers of lung cancer are mutations in receptor tyrosine kinases (RTKs) leading to activation of the phosphatidylinositol 3-kinase (PI3K)/Akt pro-growth, pro-survival signaling pathways.
A detailed immunohistochemical analysis of the PI3K/AKT/mTOR pathway in lung cancer: correlation with PIK3CA, AKT1, K-RAS or PTEN mutational status and clinicopathological features.
Here, we focused on Akt kinase-interacting protein1 (Aki1), a scaffold protein of PI3K (phosphoinositide 3-kinase)/PDK1 (3-phosphoinositide-dependent protein kinase)/Akt that determines receptor signal selectivity for non-mutated EGFR, and assessed its role in EGFR mutant lung cancer with or without gatekeeper T790M mutation.
PIK3CA gene encoding a catalytic subunit of the phosphatidylinositol-3-kinase (PI3K) is mutated and/or amplified in various neoplasia, including lung cancer.
In conclusion, we report that the shRNA-mediated knockdown of RhoGDI2 induces the invasion and migration of lung cancer due to cross-talk with the PI3K/Akt pathway and MMP-9.
The phosphoinositide 3-kinase (PI3K)/Akt signaling pathway regulates a diverse set of cellular functions relevant to the growth and progression of lung cancer, including proliferation, survival, migration, and invasion.
All of these results suggested that the lncRNA FER1L4 suppressed cell proliferation and metastasis by inhibiting the PI3K/Akt signaling pathway in lung cancer.
cIAP2 upregulated by E6 via EGFR/PI3K/AKT cascades may contribute to cisplatin resistance, revealing that the EGFR or PI3K inhibitor combined with cisplatin may improve the chemotherapeutic efficacy in HPV-infected lung cancer.
This finding set the stage for further testing of FLJ10540 as a new therapeutic target for treating lung cancer and may contribute to the development of new therapeutic strategies that are able to block the PI3K/AKT pathway in lung cancer cells.
Combined TAE684 with PI3K inhibitor synergistically inhibited the proliferation of EML4-ALK-positive cells in vitro and significantly suppressed the growth of H2228 xenografts in vivo, suggesting the potential clinical application of such combinatorial therapy regimens in patients with EML4-ALK positive lung cancer.
Taken together, these findings demonstrate that PI3K/AKT/YY1 is involved in the regulation of lung cancer cell behavior induced by IL‑13, and miR‑29a represents a promising therapeutic target.
The effect of paclitaxel combined with lobaplatin on the sensitivity of lung cancer cell line NCI-H446 through influencing the phosphatidylinositol 3-kinase (PI3K)/Akt pathway was investigated.
These findings not only shed light on the molecular mechanisms that are activated by aberrant signalling through the PI3K/AKT pathway in lung epithelial cells, but also contribute to the identification of previously unrecognised molecules whose regulation takes part in the development of lung cancer.
In this study, we investigated the potential of targeting the catalytic class I(A) PI3K isoforms in small cell lung cancer (SCLC), which is the most aggressive of all lung cancer types.
